Introduction

When you buy jeans, you have to look at two measurements: waist and inseam. Just because you have a small waist doesn't mean you have short legs. Jeans come in all shapes and sizes! Waves also can be measured in two important ways: Amplitude and Frequency. Every wave has an amplitude, and every wave has a frequency. Having a large amplitude does not guarantee a large frequency! The chart below summarizes the lesson. Your work with GarageBand will help you digest that lesson.
